Our front door is made of glass panels and has a glass transom window (is that a good idea in a "marginal" Baltimore neighborhood? No. But at least we have two dogs--one large, one noisy).
Robins have made a nest on the transom part of the door. Despite frequent egress. Despite noisy children. Despite barking dogs, porch lights, and mail delivery.
This means one can sit inside half way up the stairs and be level with the nest, and see it through the glass.
1) Wow! I hope the birds stay there and have babies, because the kids are going to be able to spend all day on the steps inside watching!
2) Robins, really. What are you thinking? Your nest sits on the door frame and is backed by clear glass. Perhaps you are just happy to be out of the (incessant) rain and are willing to put up with a lack of privacy in exchange for dryness?
I guess their nest is in a better spot than the sparrow nest in our drier vent last year. (I can imagine a sparrow pitching that one to his mate; "But look, honey. It may be loud and windy, but the eggs will always be warm!")
